The Iant Carnen (S. "Redwater Bridge") crossed that river ten miles above its confluence with the Harnen, carrying the Men Harad from the town of Tharven in the west into Harondor's East March. The bridge was built in S.A. 2288 by the Númenóreans as they began construction on the Men Harnen and extended the road eastward to Al Amrûn. The Iant Carnen carried a 20-foot wide roadbed 80 feet above the Carnen.The roadbed was supported by thirty-two semicircular granite arches, which carried it almost a half mile across the Carnen river valley. The arches had a uniform span of 60 feet and were supported by 15-foot wide and 50- foot long piers with tapered ends to resist the flow of water. A heavily fortified gatehouse protectrf each end of the bridge. Their original construction had been largely unmodified by their various garrisons.Typical of Númenórean construction, both the bridge and the gatehouses were built of granite. The weathering of many centures had left lizzle mark on the bridge.Zhe gatehouses had suffered somewhat from military action, but the damage had been superficial.
